Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed March 23, 1918. Serial No.` 224,154.

To all whom 'it may concern:

Be it known that I, EDMUND GEssMANN, a subject of the Emperor ofAustria, residing at Union Hill, county yof Hudson, and State of NewJersey, have invented certain new and useful Improvements in Two-Colored Fountain-Pens, of which the following is a specification.

This invention relates to improvements in pens and particularly to inkfilled types adapted to be carried in the pocket, known as fountainpens.

The principal object of the invention is to provide means whereby twopen points may be used in connection with a single holder, each of thepens havino' an independent supply of ink which mayibe of differentcolors.

Another obj ect is to provide means whereby one of the pens may bepermanently extended, as likely to be used more than the other, whiletheother pen may be retracted into a recess, so as to offer no impedimentto the use of the main or outwardly extendin pen. 4

hese and other like objects are attained by the novel construction andcombination of parts hereinafter described and shown in theaccompaanying drawing, formino` a material part of this disclosure, andin which Figure 1 is a side elevational view showing a pen made inaccordance with the invention.

Fig. 2 is a longitudinal sectional view taken substantially through thecenter of the same on line 2-2 of Fig. 4.

Fig. 3 is an enlarged fragmentary longitw,l

dinal sectional view taken on line 3-3 of Fig. 2, and i Fig. 4 is atransverse sectional view, taken 'on line 4-4 of Fig. 3.

Like other instruments of similar character, the parts are made mainlyof hard rubber, the pen nibs or points being of `gold or other preferredmaterial. The main part or barrel 10 is cylindrical exteriorly andformed with two longitudinal recesses,respectively 11 and 12, in whichare fitted separate caps 13 and 14. So as to retain the contents, andacting as filling inlets for the openings.

When the pens are not in use, a'cap 17 is the opposite end of thebarrel, covering the plugs, when the pen is in operation. A springsecuring means 18, is fixed upon the cap and holds the same when withina pocket. a

plu

also fitting I An extension 16 is formed to receive the sleeve orbushing 20, containing a plug 21, having a central passage 22, the plugbeing tapered at its outer end and fitted to receive the pen nib 23, andcapillary feeder 24, by which ink is conducted from the longitudinalopening 22, and passage 25.

At the opposite side of the extension 16, is ,another sleeve 28,surrounding a plug 29, having a central longitudinal opening 30, the 29,being slidable within the sleeve, whi e the opening 30 is in alinementwith the passage 32 formed in the inner end wall of the ink reservoir12. The opposite end of the plug 29 has fitted to it a pen nib 33, andcapillary feeder 34, similar to that previously described.

Formed Vthrough the extension 16, upon opposite sides are longitudinalslots 36, similar slots 28, and secured to the plug 29 are extendnspring arms 40, bent rearwardly at 41, an again turned outwardly at 42,the laterally protecting elements 40, operating in the slots 37, whilethe slots 36 formed in' the extension 16, through which they extend andare provided with operative heads 44.

The projectingelements 40, 41 and 42 are made of spring material and areformed with lshoulders 45 so that when the pen 33 lis in an extended4position', the shoulders 45 engage in recesses 46 formed in the sidewalls of the slots 36, or when the en is retracted, engage in similarrecesses ormed near the ends of the slots. 1

In operation, the two compartments 11 and 12 having been filled with inkand it is desired to use the pen 33, the extending knobs 44, aredepressed, and at the same time moved forward toward the operative endof the implement until the shoulders 45 engage with the correspondinglrecess, holding the pen point 33 extended.

AObviously when it is desired to make use of the main pen 23, the knobs44 are depressed and moved toward the rear or opposite end of the barreluntil the shoulders engage with the rear recesses at which time the pennib 33 will be retracted within the extension of the implement so as notto inter' 37, extending through the sleevel the outer extensions 42operate in fere with the free use of the pen point or i nib 23. Thuseither of the pens maybe used conveying a different color or species ofink as may be desired and it is to be understood that the implement maybe no larger than the operation is substantially identical there-`maintaining ink therein, a plug ixed in said' extension in alinementwith one of said reservoirs, a pen point carried thereby, means forconducting ink from one of said reservoirs to said pen point, a secondplug sliding in a sleeve within said extension, and havin a centrallongitudinal channel, said plug eing in alinementwith the other of saidink reservoirs, a pen point fixed therein, communicatin means betweensaid ink reservoir and sai pen point through said plug, a guiding sleevefor said movable plug slots `formed in said guiding sleeve and throughsaid extension longitudinally of said barrel, spring armsrigidlyrengaged in said movable plug extendlng outward through saidslots, knobs formed upon the ends ol said spring arms whereby they maybe actuated in said slots, recesses formed in the edges of said slot,and detents formed upon said spring arms adjacent to said knobs wherebysaid sliding plug may be held in an adjusted position at either endofsaid slots.

In testimony whereof vI have affixed my signature. l. V
